The South Dakota State Quarter was the fifth and final State Quarter issued in 2006. It also completed the 8th year in the original ten-year collection that will eventually honor all 50 states. South Dakota was the 40th state to join the Union, so this coin is the 40th in the complete collection. The South Dakota coin followed the North Dakota coin 2006 and will be followed be Montana, Washington, Idaho, Wyoming, and Utah in 2007. South Dakotas State Quarter design selection process began when state residents were asked to submit design suggestions. The process reached its final phase in January 2005 when state residents were able to vote on the final five design proposals. The winning South Dakota State Quarter design features the official state bird - a Chinese ring-necked pheasant - in flight above Mount Rushmore National Monument. Heads of wheat frame the design on the left and right to symbolize the states agricultural heritage.

The roll contains 40 uncirculated Quarters taken out from Government sewn bags. Please keep the coins in their protective tube holder provided to maintain their uncirculated condition.

In December 1997, America's most adventurous coin program became a reality when President Clinton signed legislation authorizing the U.S. Mint to issue the innovative 50 State Quarters collection. Starting in January 1999, each of the 50 states in the Union will be honored on a unique Quarter Dollar commemorative coin. Five states will be featured each year, based on the order in which they ratified the Constitution or became states. Mintages of each quarter only are to be just a fraction of the "normal" quarters are. Regular issue coins will be minted at both the Philadelphia and the Denver Mints. The mint marks can be found to the right of George Washington's portrait on the obverse: the small "P" indicates the Philadelphia Mint and the small "D" refers to the Denver.
